Reflection features have already been detected in a number of X-ray binaries. [1]} have significantly detected the relativistic smearing of the reflected spectrum in Cyg X–1. Using the X-ray spectrum, they have simultaneously constrained the ionization state and the percentage of relativistic smearing. They analyzed observations from three different missions namely: EXOSAT GSPC, Ginga and ASCA. They implemented the PEXRIV model in XSPEC to fit the reflection spectrum, and the DISCLINE model in XSPEC is used to account for the relativistic smearing. They fitted the spectrum for different values of the inclination angle and iron abundance. During the entire analysis, the photon-index ranged from 1.44 to 1.91. They also reported \(\xi \)  and R\(_{in}\)  for various observations. Our results are found to be consistent with their results, and during our observations, \(\Gamma \)  varies from 1.80–1.93. On many occasions, the values of the inner disk radius and accretion disk ionization parameter as reported by [1]}, are found to be close to the values observed in this work.
